Two-phase inhibition water mist drilling cooling device

Abstract

The invention discloses a two-phase inhibition water mist drilling cooling device. The two-phase inhibition water mist drilling cooling device comprises a two-phase atomizing nozzle (1), a right-angle metal elbow (2), an extensible metal pipe (3), a high-pressure hose I (4), a pressure-measuring metal pipe I (5), a pressure-measuring metal pipe II (7), a high-pressure hose II (10), a proportioning mixer (11) and an inhibitor box (12), wherein the two-phase atomizing nozzle is connected with one end of the right-angle metal elbow and one end of the extensible metal pipe, the other end of the right-angle metal elbow is connected with the high-pressure hose I, the pressure-measuring metal pipe I is installed in the middle of the high-pressure hose I, a gas pressure gauge is installed on the pressure-measuring metal pipe I, the other end of the extensible metal pipe is connected with the high-pressure hose II through the pressure-measuring metal pipe II and a valve, and the proportioning mixer is installed in the middle of the high-pressure hose II and is connected with the inhibitor box. The two-phase inhibition water mist drilling cooling device can carry out rapid cooling on high-temperature drilled holes, is good in fire extinguishment effect and low in water consumption, can effectively inhibit reignition, and have the high field adaptability.

Description

technical field [0001] The invention relates to a cooling device, in particular to a two-phase resistive fine water mist drilling cooling device, which belongs to the technical field of coal mine safety and is especially suitable for coal field fire prevention and control. Background technique [0002] Coalfield fires will burn a large number of coal resources in my country every year, causing huge economic losses, seriously polluting the environment, and threatening the safe production of coal mines. People generally reduce the occurrence of fires or extinguish fires through high-temperature drilling to cool down, mainly including measures such as watering, fire-extinguishing foam injection, and grouting. However, direct irrigation consumes a lot of water, but it is difficult to extinguish high-level fires. A large amount of water resources are lost along the cracks in the rock formation. The cost of injecting fire extinguishing foam and grouting is not only high, but also ...

AI Technical Summary

Problems solved by technology

However, there are few products about water mist fire extinguishing technology in my country, only water mist nozzles and water mist application systems, and the existing water mist system is complicated in layout and is not suitable for coalfield fire extinguishing; The coalfield fire situation urgently needs a rapid cooling device specially designed for high temperature drilling cooling, small water consumption, high stability, strong site adaptability, and good fire extinguishing effect.
